Normal food behavior is to eat until satiated. We've pretended it's normal to gorge yourself at McDonald's and such because saying otherwise makes some people feel bad.

People adopting normal food behavior aren't going to be drawn to eating at such a restaurant. The food that's been mentioned is trivial to make at home and requires less time than going out.

In places where there's enough mass of people to actually make this worthwhile (mainly Asia), there's tons of options, but no large ones.
